To all whom it may concern:

Be it known that I, WILLIAM L. PAUL,

a citizen of the United States, residing at San Francisco, in the county of San Franciscoand State of California, have invented certain new and useful Improvements in folding Devices for Cultivator-Standards, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to devices adapted to securing to bars of cultivating implement standards upon which shovels or other earth working tools are mounted. V

The object of my invention is to provide a construction that relieves the holding devices for the standards upon which the shovels are mounted of draft strain.

A further object of my invention is to provide a standard holding device which. can be attached to bars of cultivators, and which can be readily adjusted longitudiwhy of the bars to accommodate different widths of cultivation.

A still further object of'my invention is to provide 'a device in which the standards are secured in such a manner as to be readily adjustable vertically.

Referring to the drawings in which similar numerals indicate identical parts V Figure l is a side elevation of device, as I mount it on a cultivator, showing a standard and shovel carried thereby.

Fig. 2 is a vertical section of my device, and

Fig. 3 is a plan View.

Reference is had to my pending application of even date herewith, in which is shown a type of cultivator to which my device is particula-rly applicable, the frame supporting the gang of earth treating tools being composed of parallel bars arranged in different vertical and horizontal planes.

My fastening device consists of a casting 1 having a central passage or opening 2 for the reception of the standard or shank 3 of an earth working implement or tool such as a shovel or the like. On the opposite sides of the passage 2 are openings 4: and 5 extending at right angles to the passage 2 and in different horizontal and vertical planes; in the opening a in the upper forward part of the casting 1 is fitted a bar 6, and in the opening 5 in the lower rearward part of the casting 1 is fitted a bar 7 and rear of the passage 2.

parallel to the bar 6. The openings 1 and 5 communicate with the passage 2 and extend into the side walls of the latter so that the bars 6 and 7 project into the-passage 2 andthe shank or standard 3 contacts only with'the bars 6' and"? instead of the front Directly opposite the openings is a recess 8 and a similar recess 9, also open next the passage 2, is directly opposite the opening 5, both recesses communicating with the passage 2; Projecting through a suitable orifice in the closed end of the recess Sis a bolt 10 threaded to engage with anut ll which being of similar shape to the recess 8 is held against turning by contact with the sides thereof; the bolt 10 is held in contact with the shank 3 by a spring washer 11* inserted between the nut 11 and the closed end of the recess 8. In the recess 9 a similar bolt 12 projects and is provided with a nut 13 and a spring washer let, the spring washers not only hold the bolts against the shank 3 but they prevent said bolts from automatically turning. It is app'arent'that by loosening the bolts 10 and 12 the shank can be adjusted vertically.

In the construction sham and described it is "evident that by loosening the nuts 11 and 13 the casting .1, carrying with itthe standard '3, can be adjusted longitudinally of the bars 6 and 7, which are suitably supported on the frames of a cultivator, and the standards can be adjusted vertically to any desired position. In the use of my device it is seen that by arranging the bars 6 and 7 in different planes, or diagonally as shown, all the strain upon the standard 3 resulting from use in cultivating is exerted upon the bars 6 and 7 the casting 1 acting only as a holder for the standard 3.

What I claim is 1 1. The combination with a cultivator frame, of parallel cross bars supported thereon in different horizontal planes and in stepped relation one with the other, a standard, and means to support said standard on the cross bars.

2. The combination with a cultivator frame, of parallel cross bars supported thereon indifferent horizontal planes, and in stepped relation one with the other, a standframe, of parallel cross bars supported thereon in different horizontal planes, and in stepped relation one With the other, a stand-- ard and means to support said standard hetween the cross bars and in with.

4. The combination with a cultivator frame, of parallel cross bars supported thereon, a holding device having a vertical opening to receive a standard, openings for the cross bars on opposite sides of the vertical. opening, the opening on one side of the vertical opening being ina higher plane than the opening on the other side, and means to secure the standard in the vertical-opening and the bars in the openings therefor.

5. The combination with a cultivator frame, of parallel cross bars supported thereon, a holding device having a vertical open ing to receive a standard, openings for the contact therecross bars on opposite sides of the standard openings and extending therein and in different horizontal planes, and means to secure the standard and cross bars in said holding device in fixed relation to each other.

6. T he combination With a cultivator frame of two horizontally disposed parallel cross bars supported thereon, a holding device having a central vertical opening to receive a standard, openings for the cross bars in front and rear of said opening and extending therein, the front opening being in a higher plane than the rear opening, and means to secure the standard and cross bars in said holding device in fixed relation to each other. V

7. The combination With a cultivator frame, of horizontally disposed parallel cross bars, a holding device having a central open ing to receive a standard, openings for the cross bars on opposite sides of the standard opening and extending therein to permit contact of the standard With the bars, the bar opening on one side of the standard opening being in a higher plane than the bar opening on the other side, and means to hold said standard in fixed relation to each bar.

8. The combination With a cultivator frame, of two horizontally disposed parallel cross bars, a holding device having a vertical opening to receive a standard, openings for the cross bars on opposite sides of the standard opening and extending therein to permit contact of the standard with the bars, the bar opening on one side of the standard opening being in a higher plane than the bar opening on the other side, and means on opposite sides of the standard opening to hold the standard and bars in contact.

9. The combination With a cultivator frame, of two horizontally disposed cross bars, a holding device having a vertical opening to receive a standard, openings for the cross bars on opposite sides of the standard opening and communicating therewith. to permit contact of the standard with the bars, the bar opening on one'side of the standard opening being in a higher plane than the bar opening on the other side, and boltson the standard holding device on opposite sides of the vertical opening therein to hold the standard and bars in fixed contact.

In testimony whereof I affix my signature, in presence of tWo' Witnesses. i
